HitTest Method (AnnObject)
Summary
Performs hit-testing on this AnnObject.
Syntax
public virtual bool HitTest(Leadtools.LeadPointD point,double hitTestBuffer)
Public Overridable Function HitTest( _ByVal point As Leadtools.LeadPointD, _ByVal hitTestBuffer As Double _) As Boolean
public virtual bool HitTest(Leadtools.LeadPointD point,double hitTestBuffer)
-(BOOL) hitTest:(LeadPointD)ptbuffer:(double)buffer;
public boolean hitTest(LeadPointD point, double hitTestBuffer)function Leadtools.Annotations.Core.AnnObject.HitTest(point ,hitTestBuffer)
Parameters
point
The Leadtools.LeadPointD to be tested.
hitTestBuffer
Threshold buffer value, in container units.
Return Value
true if the test point intersects with the object; otherwise, false.
Remarks
hitTestBuffer is used to make the test point "bigger" to compensate for errors and provide smoother hit-testing. For example, if buffer is 2, a square with a length of 4 units around the test point will be used to perform the hit-testing.
By default, an annotation object will return true if hit-testing was satisfied. Derived objects can override this method to fine tune the return value.
